Custom Colors and Additives

The right color and additive package can transform a standard thermoplastic resin into a material that better fits your product, production process, and performance requirements. Reaction Polymers provides custom plastic color matching and thermoplastic additives from its Murray, Utah, location, helping manufacturers create materials that meet specific visual and functional goals. Whether you need a readily available stock color, a custom color concentrate, or additives designed to improve a particular property, the team can help identify a practical solution for your application. Reaction Polymers is a distributor for Clariant Masterbatches and maintains an inventory of stock colors at competitive prices. Many commonly requested colors may be readily available, allowing manufacturers to obtain color concentrates without waiting for a fully customized formulation. Certain materials can also be drop-shipped directly to the customer, helping reduce unnecessary handling and simplify the ordering process. When a stock option does not provide the appearance your product requires, Reaction Polymers can assist with custom plastic color matching. A target color may be supplied as a Pantone reference or a physical sample. A physical sample can be especially useful when a manufacturer needs to reproduce the appearance of an existing part, maintain consistency with a branded product line, or develop a color that does not correspond closely to a standard reference. Accurate color matching involves more than selecting a pigment that appears similar. The base resin, natural resin color, opacity, surface finish, processing temperature, part thickness, lighting, and additive content can all influence the final appearance. The same color concentrate may look different in a clear resin than it does in an opaque resin. It may also appear different in a thin molded wall compared with a thicker part. Sharing detailed application information helps Reaction Polymers determine the most appropriate color solution for the intended material and production method. Custom color concentrates can help manufacturers create a consistent appearance while avoiding the need to purchase multiple precolored resin grades. Concentrates are added to the base material at a controlled ratio during processing. This approach can give manufacturers greater flexibility when producing several colors from the same base resin or adjusting color demand from one production run to the next. Reaction Polymers can also assist companies working with reprocessed or recycled resin. Recycled plastic may contain natural variation in shade, especially when it comes from multiple production runs or previously colored material. A suitable color concentrate may help create a more uniform appearance or convert the material into a darker, more consistent color. The feasibility of each project depends on the starting resin, existing color, contamination level, desired shade, and acceptable tolerance. In addition to color masterbatches and concentrates, Reaction Polymers offers a broad selection of thermoplastic additives. These may include UV inhibitors, fire retardants, clarifiers, lubricants, impact modifiers, and other materials intended to influence how plastic performs during manufacturing or throughout the finished product’s service life. UV inhibitors can help protect certain plastic products from the effects of prolonged sunlight and ultraviolet exposure. Outdoor components, equipment housings, containers, construction products, and other applications may experience fading, discoloration, surface degradation, or reduced physical performance without appropriate UV protection. The correct additive will depend on the resin, exposure conditions, expected service life, and product requirements. Fire-retardant additives may be considered when an application must achieve particular flammability characteristics. The appropriate solution depends on the base polymer, finished part, processing method, required standard, and additive loading. Because fire-retardant packages can affect color, mechanical properties, melt behavior, and processing conditions, manufacturers should provide detailed performance requirements when discussing the project. Clarifiers are commonly used when a manufacturer wants to improve the transparency or visual clarity of a compatible material. They can help refine the appearance of certain molded products, but results vary based on the resin, processing conditions, part design, and other ingredients in the formulation. Reaction Polymers can review the application and help determine whether a clarifying additive is suitable. Lubricants and processing aids may help improve material flow, mold release, surface appearance, or processing efficiency in certain applications. Impact modifiers may be used to increase toughness or help a material withstand cracking and sudden force. Each additive changes the overall formulation, so compatibility and dosage must be carefully considered. More additive is not always better. The objective is to use the appropriate material at a controlled level to achieve the desired result without creating unnecessary processing or performance issues. The process begins with understanding the customer’s base resin and intended application. Helpful information includes the resin type, manufacturing process, desired color, physical sample or color reference, finished part requirements, expected environment, current performance concern, and anticipated volume. Customers should also identify any existing fillers, colors, or additives that may already be present in the material. Reaction Polymers can support projects ranging from straightforward stock-color orders to highly specific custom formulations. Contact the team to discuss your desired color, performance target, base resin, estimated volume, and production process. With access to stock colors, custom matching, and a broad range of additives, Reaction Polymers can help you develop a thermoplastic material that looks and performs the way your application requires.
